There is lots of freedom around how to treat people and as long as what you do is sensible and within your delegated scope of practice then you are pretty much free to do it. Clinical judgement is very important and given lots of attention, guidelines are just that, a guideline, and a favourite saying of one of my mentors is "patients do not read textbooks" so you really have to have your thinking cap on and use your tools wisely.
We can leave people at home, refer them elsewhere, send a single responder and lots of things. We are told basically to see a patient, determine what they need and how best to get it and refer them there, if necessary by taking them there. Only about 70% of patients are transported to hospital. Looking to the future there is now a big change to how 111 calls are dealt with where the less urgent/minor stuff isn't sent an ambulance but put through to the phone nurses or sent a single response in a car.
